Ehler Fisher Transform Indicator Formula, Strategy

Ehler Fisher Transform Indicator

Ehler Fisher Transform indicator is designed to clearly spot major price reversals and visualize them. It is also a leading/lagging indicator of all the indicators present in Zerodha Kite. This is reflected in spots where the rate of change is the biggest. It is an indicator built on an oscillator that was developed by John Ehler, the author of the book MESA and Trading Market Cycles: Forecasting and Trading Strategies from the Creator of MESA (Wiley Trading Book 124).

Ehler Fisher Transform is based on the assumption that prices do not have a normal probability density function (Gaussian Probability Density Function). A Gaussian PDF is the bell-shaped curve of distribution where 68% of the samples fall within one standard deviation around the mean.

Profit-Making Strategies with Ehler Fisher Transform Indicator

Many successful traders use the indicator for making huge profits. To demonstrate the strategies in simple ways, I broadly divide the section into two levels. One is for newbies and the other is for advanced professional traders.

Simple Trading Strategies

  • When the indicator crosses the zero level, a signal appears to change the trend and it indicates buy or sell.
  • Once the indicator crosses the zero from below, you may open a Long or buy position.
  • Reversely, when it crosses the zero line from above, you may try for a short or sell position.
  • Another method of exit is when the signal line (EF Trigger) crosses the Ehler Fisher (EF).
  • Oppositely, if the Ehler Fisher (EF) crosses the EF Trigger, traders may take entry.
Simple Trading Strategies

See the above ICICIBANK chart. There, the white straight line is the Zero line and traders can identify the entry-exit point by the crossover of EF and EF trigger.

Advanced Trading Strategies

  • The indicator values above +0.5 are overbought and therefore offer an opportunity to sell.
  • And the values below -0.5 are oversold and traders take the opportunity to buy.
  • The best usage of the Fisher transform indicator is in combination with other indicators to achieve better performance.
Entry Exit with Ehler Fisher Transform Indicator

Here, for example, purpose, I place SuperTrend along with Ehler Fisher. Now, look carefully at the above chart. The Supertrend is of Period 10 and Multiplier 3 and the EF is set at the default position. Now, when both the Supertrend and EF entry matches, we will take a buy position. And in the same way, close the position on the sell signal.

Now look, between the buy-sell signals of the Supertrend, the EF indicator creates many noises (Ups-Down) there. These ups and downs movements are not worth taking. Traders can make huge profits there if they ignore those noises.
